Supposedly there are maimed NCR soldiers between Forlorn hope and Nelson, which the Legion has booby-trapped.

I've been looking for them for ages, and I still haven't found them. I've also heard that they were removed in a patch. Is this true?

I don't think so, I saw them on my last playthrough.

Only one there for me. Most of the frag mines are there though.

Jolipinator pretty much said the issue, sometimes the soldiers don't spawn, yet the frag mine traps will be in the place a soldier would be.

I heard about this on other forum as well.....IIRC NV isn't 16/18/20(whatever your countries use)+?

Never seen bodies but i... discovered some frag mines on my way back from Dead Money
